Used in immunological research to quantify CD4 molecule levels in biological samples, this ELISA kit enables accurate measurement of CD4 expression in goat samples. It is widely applied in studies related to T-cell function, immune response monitoring, and infectious diseases such as caprine arthritis encephalitis virus (CAEV) or other retroviral infections in goats. The kit supports research in veterinary immunology, vaccine development, and disease progression studies by providing a reliable tool for detecting soluble or cell-derived CD4 antigens. Its high sensitivity and specificity make it suitable for use in both experimental and diagnostic laboratory settings.
